w objectrof the invention'isthe provision of improvements in a-printing maehine, whereby multi-color work such as the-pro d uctionof wall paper, may be accomplished efliciently, and wherebytheresulting prod 110 ucts will be characterized by refinedprin-t in which the coloring matter or ink will'be evenly and uniformly distributed throughout.v

Another object of the invention is the provision ofimprovements in printing machine whereby numerous appurtenan-ees, such as ink spreadingdevices or rollers,-may be omitted, and whereby unnecessary adjustments and neonseqnent delays may be so avoided.

Another object of the invention is the provision of a fluid or eolor distributor for. printing machines which will distribute the ink. orcolor e-venlyiand uniformly di- 25 rectly to, the. printing surface of a printing roll. 7

The nature of the inventiona'nd its dis+ tinguishing features and advantages will appear when the following specification read in connection with the accompanying drawings in which Figure 1 is a side elevationiof oneend. of a wall paper printing machineenrb'odying the features of the invention;

Figure 2 is:- a vertical. section of :anink distributor constructed in accordance: with the invention; T

- Figure 3 is a plan View of one end: of the fountain ofthe ink distributor shown in Figure 2.

In Figure l of the. drawings. there is shown one-end of a. wall paperprintingmachine which is selected: to. illustrate the device of the invention. The invention a contemplates the provision of separate ink distributors; one for each colors-Which transfers the ink or eolor'tothe related printing roller. The ink .or :color distributorsqare arranged in the machine at regular spaced intervals. In. Figure 1. of? the drawings two ink or eolor distributors are 'sh'own. Each distributor-10 feeds or distributes ink to theprintingsurface-of a printingroll designated 'll, which prints on the paper 12 fed thereto from a roll indicated at'13. A compression roll l andendless web '15- cooperatewitheach one of the .printing'rolis l1 toobtainthe desired pressure. Each of the printing rolls is positivelydriven by any suitable meanssuch as the employment of gearssecured to the shafts of the printing rolls, and a drive chain 16 which co operates therewith. Eachink or color-distributor 10 comprisesa fountain 17' and an or color feeder or distributor l8. 'The founta-in'l'i' comprises areceptacle or 1 tray 19 of the proper" proportion, and is made of any suitablematerial such as sheet'metal, and a second receptacle or tray 20 of the same general proportions as the tray 19. The tray 19 has an outer rim 21. and the tray 20 has an outer iii-n22 which is adapted to rest on the rim 21 to supportthe tray" 20*on the tray 19.

The bottom 23 of the tray 20 is formed of a piece ;of textile-material or fabrio which is secured in place in any practical manner such as by'theemployment of a band 24. The bottom 23 is treated with a suitable liquid-proofing substance to render the same impervious-t0 liquid. -A pad 25 is arranged Within the tray 20 and rests in contact-with the fabric bottoni'23, and is adapted toabhooks 28 extending laterally from the opposits sides of the tray 20 on the inside thereof. It will therefore be understood that thepad 25 will be prevented from sliding sidewise, and that it may be readily removed from the tray 20. It will also heapmer is rotated by the latter.

30. In order to maintain the ink or color 7 at a predetermined level below the uppermost surface area of the pad 25 there is provided one or more overflow pipes 31 in communication with the interior of the tray 20.

The feeder or distributor 18 is in the form of a roll mounted for rotation so that its cylindrical surface will roll in direct contact with the pad 25 throughout the length of the roll. It is to be understood that the feeder or distributor 18 may be adjusted with respect to the pad 25 so as to exert sufficient pressure on the pad 25, to take up the proper amount of ink or color from the pad 25. In Figure 2 of the drawing the ink or color is indicated at 32, a supply of which is constantly maintained in the tray 20 to keep the pad 25 saturated. The feeder or distributor roll 18 is in contact with the printing surface of the printing roll 11 and the for It will therefore be understood that the ink or color will be distributed over the printing surface of the printing roll 11 from the roll 18.

From the foregoing it will be apparent that the ink or color will be distributed to a printing surface of a printing roll evenly and uniformly Without requiring additional means such as ink spreading devices or rolls for this purpose. It will also be apparent that by providing the overflow means in the form of a pipe or pipes 31, ink or color will not pass directly to the periphery of the feeder or distributor roll 18. It will also be apparent that by providing the water heneath the fabric bottom 23 of the tray 20, a proper cushioning or resilient action will be maintained in conjunction with the pad 25, for the purpose of obtaining the proper co-operation of the pad 25 with the feeder or distributor'roll 18. By reason of the fact that the fabric bottom 23 is treated with a liquid-proofing composition, the water in the tray 19 will be prevented from mixing with the ink or color in the tray 20.

Claims:

1. In an ink distributor for printing machines, the combination of an ink tray having a bottom made of flexible material, an absorbent pad resting on said bottom and immersed in the ink in the tray, and an ink distributor in rolling contact with said pad.

2. In a liquid ink or color distributing de vice for printing machines, the combination of a tray for the ink or color, said tray having a bottom made of flexible material, a second tray on which the first tray is superposed, said second tray having a quantity of liquid therein level with said bottom, an absorbent pad resting on said bottom and part ly immersed in the ink or color in the first tray, and a distributor in rolling contact with said pad, for the purpose of distributing ink or color from the pad to a printing surface.

8. In an ink distributor for printing machines, the combination of an ink tray having a bottom made of flexible material, an absorbent pad resting on said bottom, and immersed in the ink in the tray, and yieldable means cooperating with said bottom to resiliently support said pad.

4. In an ink distributor for printing machines, the combination of an ink tray having a bottom made of liquid-proof fabric, an absorbent pad resting on said bottom, and immersed in the ink in the tray, and a container having liquid therein, and said liquid cooperating with said bottom to resiliently support said pad.

5. In aliquid ink or color distributing device for printing machines, the combination of a tray for the ink or color, said tray having a bottom made of flexible material, a second tray on which the first tray is superposed, said second tray having a quantity of liquid therein level with said bottom, and an absorbent pad resting on said bottom and partly immersed in the ink or color in the first tray.

6. In an ink distributor for printing machines, the combination of an ink tray having a bottom made of flexible material, an absorbent pad resting on said bottom and immersed in the ink in the tray, and cooperative and detachable members on the tray and pad to keep the pad from slipping relative to said bottom and allowing the pad to be removed from the tray.

7. In an ink distributor for printing machines, the combination of a receptacle having liquid therein, an inking pad, and means coacting with said liquid to resiliently support said pad.

8. In an ink distributor for printing machines, the combination of a receptacle having fluid therein, an absorbent pad, means coacting with said fluid to resiliently sup port the pad, and means to deliver fluid ink to said pad to saturate it.

9. In an ink distributor for printing machines, the combination of a receptacle having liquid therein, an inking pad, and means coacting with said liquid to resiliently support said pad, said means including a flexible sheet which is impervious to liquid and on which said pad rests, and said sheet being disposed on the surface of said liquid.
